“…In Refs. [17,18], events are interpreted through synched light clocks (introduced in Ref. [19]) in an emerging thermal time, and evolution is intended through a realm of probability amplitudes (with a symmetric time structure) and an emerging empirical spacetime (as events break the unitary symmetry).…”

This paper elaborates on the interpretation of time and entanglement, offering insights into the possible ontological nature of information in the emergence of spacetime, towards a quantum description of gravity. We first investigate different perspectives on time and identify in the idea of a “thick present” the only element of reality needed to describe evolution, differences, and relations. The thick present is connected to a spacetime information “sampling rate”, and it is intended as a time symmetric potential bounded between a causal past of irreversible events and a still open future. From this potential, spacetime emerges in each instant as a space-like foliation (in a description based on imaginary paths). In the second part, we analyze undefined causal orders to understand how their potential could persist along the thick present instants. Thanks to a C-NOT logic and the concept of an imaginary time, we derive a description of entanglement as the potential of a logically consistent open choice among imaginary paths. We then conceptually map the imaginary paths identified in the entanglement of the undefined orders to Closed Time-like Curves (CTC) in the thick present. Considering a universe described through information, CTC are interpreted as “memory loops”, elementary structures encoding the information potential related to the entanglement in both time and space, manifested as undefined causality and non-locality in the emerging foliation. We conclude by suggesting a possible extension of the introduced concepts in a holographic perspective.

“…Yet it is essential in order to endow the theory with physical meaning: testing the theory is only possible by recording specific events, such as the hit of an electron on a screen or the absorption of a photon by an atom, which occur at particular times. The absence of a formal representation perhaps explains why, despite its central relevance, the nature of the event-time and its relationship with the parameter-time has been scarcely discussed in the literature on quantum foundations (as exceptions, see [ 61 , 62 ], where a relational reconstruction of the event-time is proposed). In what follows, the difference between parameter-time and event-time will be related to the modal dimension of quantum mechanics.…”

“…It is precisely this network of actual events what constitute space-time: “In this interpretation, spacetime is no more—and no less—than the set of actualized transactions” ([ 65 ]: 73). In other words, the PTI assumes a relationalist conception of space-time such that “the term ‘spacetime’ describes the structured set of events themselves” ([ 65 ]: 75; for a detailed account of the emergence of space-time in the PTI, see [ 62 , 72 ]).…”

In the discourse of quantum mechanics it is usual to say that non-commuting observables cannot have definite values at the same time, or that they cannot be simultaneously measured. But, what does the term ‘cannot’ mean in this context? Does it stand for impossible? Should Heisenberg’s principle be read in terms of uncertainty or of indeterminacy? On the other hand, whereas the debates about the nature of time in classical and relativistic mechanics have been many and varied, the question about the nature of time in quantum mechanics has not received the same attention, especially when compared to the large amount of literature on interpretive issues. The purpose of this paper is to show that, under a realist interpretation of quantum mechanics, these two matters, possibility and time, are strongly related. The final aim is to argue that, when possibility and actuality are conceived as irreducible modes of being, they are correlated to two different notions of time that can be distinguished in the quantum realm: parameter-time and event-time.

We elaborate on the compatibility of a Presentism perspective with Special Relativity. Specifically, we first introduce a description of evolution in present instants and connect it with the recent studies on the discreteness of time in Quantum Mechanics. Then, we consider the insights from Information Theory to describe how we may conceive a relativistic spacetime from an evolving space foliation through the concept of information sampling. In the final part, we elaborate on GR in the context of a thick Present and speculate on the possible extensions of the proposed framework.
